i looked over the CS brochures and found out that you're gonna be missing the re-tunable amps of the PC series.
but while looking over the SVS brochures, I saw the ultra 13 brochure, and remembered that it was gonna use the 16-46 cylinder as an enclosure too ...
it's gonna be ultra 13 or no other ported svs for me.
and what's more ... the ultra 13 can be tuned to 10hz or SEALED!!
